Abstract

Here we discuss manifestations of the photonic noise avalanche in Su-Schrieffer-Heeger chains with static off-diagonal stochastic disorder. We demonstrate that a photonic noise avalanche arises in both the short-time and the long-time regimes. We predict a topology-dependent effect of sudden coherence destruction and appearance of topology-dependent field statistics. We also show that for sufficiently strong noise, when the topological localization is replaced with the Anderson localization, the long-time avalanche might occur withing the field localization region. This gives rise to a possibility of creating strongly super-bunched states.
